Environment

VMware vSphere 6.x

Cause

This may be due to missing contents in the config file of the host.

Resolution

Please follow the steps :

• Open a SSH to the host.
• Go to /etc/vmware.
• Check for the config file. Do a less or cat on the config file.
• Validate the contents of the file with below entries :

                        libdir = "/usr/lib/vmware"
                        authd.proxy.nfc = "vmware-hostd:ha-nfc"
                        authd.proxy.nfcssl = "vmware-hostd:ha-nfcssl"
                        authd.proxy.vpxa-nfcssl = "vmware-vpxa:vpxa-nfcssl"
                        authd.proxy.vpxa-nfc = "vmware-vpxa:vpxa-nfc"
                        authd.fullpath = "/sbin/authd"

• If the contents does not match , copy and paste the above content using a vi editor.
• Restart the management agents. /etc/init.d/hostd restart and /etc/init.d/vpxa restart.
